The first law of government is: "if it doesn't work, do more of it."
Shutdowns are counter-productive - so I expect we'll see a resurgence of this nonsense.
Masks spread the disease - so I expect to see increased demands for more and better masking.
National Quarantines don't work: so places like Taiwan that show great success in containing the disease but know that opening up will destroy that success are going to keep the barriers in place - it's much like airport security: a show for fools and a massive victory for the bad guys, but not something government will give up without a major fight.
So what does work? doing nothing. Pull a Sweden: bite the bullet, take some early loses and let human physiology do its work.
